The grid-contrib repository contains contributed software for Hyperledger Grid, a platform for building supply chain solutions that include distributed ledger components.

This repository is intended for community-contributed software, including example libraries, data models, and reference implementations for smart contracts (also called "transaction families"). This software is designed to work with the Hyperledger Grid platform software in the grid repository.

For example, the Grid Track and Trace transaction family provides a smart contract that tracks goods as they move through a supply chain. For more information, see the Grid Track and Trace documentation and the grid/track_and_trace subdirectory in this repository.

How to Contribute

We welcome contributions to this repository, either as changes to existing software or as new example tools and reference implementations. Please follow the guidelines for contributing. For more information, please join the #grid discussion channel or Hyperledger Grid mailing list.
